Dear all, Can we really use temperature variable in KWANT? If yes,then with what function.Also, How to apply magnetic field perpendicular to the sample like I am having the graphene sheet and I want to apply per mag. field on it.this is what I am trying! ################################################ def hopx(site1, site2, B=0): # The magnetic field is controlled by the parameter B y = site1.pos[1] return -t * exp(-1j * B * y) sys[lat.shape(circle, (0, 0))] = 4 * t # hoppings in x-direction sys[kwant.builder.HoppingKind((1, 0), lat, lat)] = hopx # hoppings in y-directions sys[kwant.builder.HoppingKind((0, 1), lat, lat)] = -t # It’s a closed system for a change, so no leads ##################################################
